Reflectivity of the quantum grating and the grating polariton

Physical Review B, 1995
We solve the problem of the scattering of an electromagnetic plane wave from a planar array of equispaced cylindrical scatterers with strong resonances. We apply this theory to calculate the reflectivity of an array of quantum wires using the electromagnetic properties of the single wire as the only input.

Grating triplet

Applied Optics, 1995
A grating-pair device is useful for producing negative group velocity dispersion of temporal optical signals. When high dispersion is needed or large bandwidth is involved, higher-order dispersion terms become significant. The grating triplet is a new approach to create dispersion that can produce negative or positive group-velocity dispersion without ...

Novel immersion grating, VPH grating and quasi-Bragg grating

SPIE Proceedings, 2006
We have successfully fabricated germanium immersion gratings with resolving power of 45,000 at 10 μm by using a nano precision 3D grinding machine and ELID (ELectrolytic In-process Dressing) method. However the method spends large amount of machine times.

Grating interferometers for producing large holographic gratings

Applied Optics, 1990
Methods for producing large holographic diffraction gratings are described. In particular, the advantages of using a grating interferometer illuminated with a noncollimated beam from either an extended monochromatic source or an extended polychromatic source are described along with some of the problems that arise and methods to solve them ...

Mechanisms of Grating Formation and Grating Materials

1986
In the following section, different mechanisms of light-induced changes of optical material properties are described. Often these changes are considered to be due to some specific material excitation (e.g., electron density, temperature). This is, however, a simplified description.
